So it may help. My 2.62 were quiet when it was stock. I added axles, aluminum ds , 3.09s and front and rear braces and it has some loud whine. Took both braces off and still there but the front being off reduced it. I put the 2.62 back in and still have gear whine but less. So it has to be the ds or the axles. Figured it was the 3.09s but they were only some of it. My car is a daily driver so it matters a little more to me
